Abstract: Research have found that digital emotion contagion, polarized emotion in particular, was associated with many adverse outcomes, such as spread of fake news, political segregation, etc. This project aims to examine whether dialectical thinking, a thinking style that is more prevalent among East Asian cultures than Western cultures, can decease the expression and contagion of polarized emotions on social media. We hope this project can help with deepening the understandings of digital emotion contagion process from a psychological perspective and with theoretical frameworks. This project may provide scientific guidance and insights for policy makers to develop interventions that can cultivate a peaceful and rational social mentality.

Key words: Digital emotion contagion, Emotion expression, Polarized Emotion, Culture, Dialectical thinking
